Description

背景技术
在新无线(New Radio，NR)系统(或称5G系统、5G网络)中，支持非授权频谱(unlicensed frequency bands)上的数据传输，通信设备在非授权频谱上进行通信时，需要基于先听后说(Listen Before Talk，LBT)的原则。例如，基站在免授权频谱的信道上向终端设备发送信号之前，需要先进行信道检测，只有当信道检测结果为空闲时才能进行信号发送；如果基站在免授权频谱的上进行信道检测的结果为信道忙，则不能进行信号发送。
终端设备在非授权频谱上会接收基站发送的参考信号以进行RLM测量。当终端设备测量的参考信号质量很差时，终端设备无法知晓这是基站由于信道忙而无法发送该参考信号导致的，还是由于终端设备的信道质量差导致的。这种情况下，基于该参考信号的RLM测量结果就无法准确地判断实际的信道情况。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)系统、先进的长期演进(Advanced long term evolution， LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、非授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。
示例性的，本申请实施例应用的通信系统100如图1所示。该无线通信系统100可以包括网络设备110。网络设备110可以是与终端设备通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备100可以是GSM系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是NR系统中的网络侧设备，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备、下一代网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该无线通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。终端设备120可以是移动的或固定的。可选地，终端设备120可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信 设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的终端设备或者未来演进的PLMN中的终端设备等。其中，可选地，终端设备120之间也可以进行终端直连(Device to Device，D2D)通信。
具体地，网络设备110可以为小区提供服务，终端设备120通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备110进行通信，该小区可以是网络设备110(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该无线通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
可选地，该无线通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
目前，免授权频谱上的NR系统(NR-U)中的目标场景包括SA场景和DC场景，都需要在非授权频段上执行RLM操作。网络设备在非授权频段上在发送信号之前，需要进行信道侦听以判断信道是否空闲，只有在判断信道为空闲才可以进行信号发送。因此，网络设备在向终端设备发送用于进行无线链路监测的参考信号RLM-RS时，可能会由于信道忙，导致RLM-RS无法发送，从而影响终端设备进行无线链路监测。
现有机制中，当终端设备基于RLM-RS进行测量，得到信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)，当该SINR高于同步门限Qin时，终端设备上报同步(in sync，IS)指示；当测量得到的SINR低于失步门限Qout时，终端设备上报失步(out of sync，OOS)指示。
但在非授权频段上，当终端设备测量的SINR很低时，终端设备无法知晓这是网络设备由于信道忙而无法发送RLM-RS所导致的，还是由于终端设 备的信道质量差导致的。如果是由于网络设备在发送RLM-RS时信道暂时忙导致了RLM-RS无法发送，但实际上一旦信道空闲，信道质量依然较好，则这种情况下终端根据对RLM-RS的测量结果就无法准备判断当前实际的信道情况。
因此，本申请实施例提出，终端设备不仅仅是基于第一资源上进行无线链路监测的结果进行IS指示或OOS指示的上报，而是同时结合第一资源上进行无线链路监测的结果，以及第二资源上进行无线链路监测的结果或者第二资源上的下行信号接收情况，确定是否上报IS指示和/或OOS指示，以提高非授权频段上的进行无线链路监测的准确性。
本申请实施例中用于终端设备进行RLM的参考信号RLM-RS例如可以包括信道状态指示参考信号(Channel State Information Reference Signal，CSI-RS)或同步信号块(Synchronization Signal Block，SSB或SS Block)等参考信号。
图2是本申请实施例的无线链路监测的方法200的示意性流程图。图2所述的方法可以由终端设备执行，该终端设备例如可以为图1中所示的终端设备120。如图2所示，该无线链路监测的方法200可以包括以下步骤中的部分或全部。其中：
在210中，终端设备在第一资源上进行无线链路监测。
可选地，该第一资源是网络设备配置的用于RLM的资源。
例如，终端设备可以在所述第一资源上进行信号与噪声干扰比SINR测量，若测量得到的该SINR大于同步门限Qin，终端设备确定第一资源上的RLM测量结果为IS；若测量得到的该SINR小于失步门限Qout，终端设备确定第一资源上的RLM测量结果为OOS。
在220中，终端设备根据该第一资源上的RLM测量结果，以及第二资源上的RLM测量结果或下行信号接收情况，确定是否上报IS指示和/或OOS指示。
本申请实施例中，终端设备在用于进行RLM测量的第一资源上进行RLM后，得到第一资源上的RLM测量结果为IS或OOS，此时，终端设备不仅要考虑第一资源上的RLM测量结果，还要同时考虑第二资源上的RLM测量结果或者第二资源上的下行信号接收情况，从而确定该终端设备的物理层是否需要向其高层上报IS指示和/或OOS指示，因此能够提高非授权频段 上的进行无线链路监测的准确性。
应理解，这里所述的第一资源可以包括一个测量资源，也可以包括多个测量资源。所述的第二资源可以包括一个资源或多个资源，且该第二资源可以为用于进行无线链路监测的测量资源或者为用于接收下行信号的下行资源，本申请实施例中不作限定。
下面具体描述本申请实施例中用于进行无线链路监测的两种方式。
方式1
该方式中，终端设备根据该第一资源上的RLM测量结果，以及该第二资源上的下行信号接收情况，确定是否上报IS指示和/或OOS指示。
可选地，终端设备根据该第一资源上的RLM测量结果，以及该第二资源上的下行信号接收情况，确定是否上报IS指示和/或OOS指示，包括：若该第一资源上的RLM测量结果为IS，终端设备确定上报该IS指示。
可选地，终端设备根据该第一资源上的RLM测量结果，以及该第二资源上的下行信号接收情况，确定是否上报IS指示和/或OOS指示，包括：若该第一资源上的RLM测量结果为OOS，终端设备根据是否在该第二资源上接收到网络设备发送的该下行信号，确定是否上报该OOS指示。
可选地，若终端设备在该第二资源上接收到该下行信号，该方法还包括：终端设备确定上报该IS指示。
可选地，终端设备根据是否在该第二资源上接收到网络设备发送的该下行信号，确定是否上报该OOS指示，包括：若终端设备在该第二资源上接收到该下行信号，终端设备确定不上报该OOS指示；和/或，若终端设备在该第二资源上没有接收到该下行信号，终端设备确定上报该OOS指示。
其中，该第二资源例如可以包括第三资源之前的预定时长内的至少一个下行资源，该第三资源为用于终端设备上报该第一资源上的RLM测量结果的资源。该第一资源可以位于该预定时长内，此时，该第二资源为该预定时长内除该第一资源之外的测量资源或下行资源；或者，该第一资源也可以位于该预定时长之前或之后。
也就是说，终端设备在第一资源上的RLM测量结果为OOS时，终端设备可以在用于上报该OOS指示的第三资源之前的一段时间内，即该第二资源内，判断是否接收到了下行信号。如果在该第二资源上，终端设备接收到了下行信号，说明第一资源上的RLM测量结果为OOS很可能是由于信道忙 而非信道质量差而导致的，那么这时终端设备可以不在第三资源上上报OOS指示，或者是改为上报IS指示。
其中，可选的，该下行信号可以是以下信号中的至少一种：唤醒信号(Wake-Up Signal，WUS)、相位跟踪参考信号(Phase Tracking Reference Signal，PT-RS)、下行解调参考信号(Demodulation Reference Signal，DMRS)、物理下行控制信道(Physical Downlink Control Channel，PDCCH)、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)、第一资源外的其他资源上发送的CSI-RS、第一资源外的其他资源上发送的SSB等。
方式2
该方式中，终端设备根据该第一资源上的RLM测量结果，以及第二资源上的RLM测量结果，确定是否上报同步IS指示和/或失步OOS指示。
一个测量周期内可以配置多个测量资源(或者说是多个测量窗口)，该多个测量资源包括该第一资源和该第二资源。可选地，该第二资源为位于该第一资源之后的至少一个测量资源。
可选地，终端设备根据该第一资源上的RLM测量结果，以及第二资源上的RLM测量结果，确定是否上报IS指示和/或OOS指示，包括：若该第一资源上的RLM测量结果为IS，终端设备停止在该第二资源上进行RLM并确定上报该IS指示。
可选地，终端设备根据该第一资源上的RLM测量结果，以及第二资源上的RLM测量结果，确定是否上报IS指示和/或OOS指示，包括：若该第一资源上的RLM测量结果为OOS，终端设备继续在该第二资源上进行RLM，直至该多个测量资源上的RLM测量结果均为OOS时确定上报该OOS指示。
具体地，终端设备在一个测量周期内的一个测量资源即该第一资源上进行无线链路监测得到的RLM测量结果为IS时，终端设备可以不在该测量周期内继续进行无线链路监测，而是直接确定RLM测量结果为IS，并上报IS指示。如果在该第一资源上进行无线链路监测得到的RLM测量结果为OOS，则终端设备可以继续在该第一资源之后的第二资源上进行无线链路监测，如果该测量周期中的所有测量资源上的RLM测量结果均为OOS，终端设备确定链路监测结果为OOS，并上报OOS指示。
简而言之，一个测量周期中的某个测量资源或某些测量资源上的RLM测量结果为IS时，则上报IS指示；而一个测量周期中的所有测量资源上的 RLM测量结果均为OOS时，才会上报OOS指示。
上面描述的无线链路监测的方法是通过改变终端设备的实现行为，从而尽量避免由于信道忙而不能成功发送RLM-RS所导致的频繁地上报OOS指示。本申请实施例还提供了一种无线链路监测的方法，该方法借助网络设备，使得终端设备能够判断当前测量资源上的RLM测量结果是否是有效的，从而避免不必要的OOS指示的上报，下面结合图3和图4进行具体描述。
图3是本申请实施例的无线链路监测的方法300的流程交互图。图3该的方法可以由终端设备和网络设备执行，该网络设备例如可以为图1中所示的网络设备110，该终端设备例如可以为图1中所示的终端设备120。如图3所示，该无线链路监测的方法300可以包括以下步骤中的部分或全部。其中：
在310中，网络设备确定用于终端设备进行无线链路监测的第一资源是否位于COT内。
在320中，若该第一资源位于该COT内，网络设备向终端设备发送指示信息，该指示信息用于指示该第一资源为有效测量资源。
在330中，终端设备接收网络设备发送的指示信息，该指示信息指示用于进行无线链路监测的第一资源是否为有效测量资源。
在340中，若该指示信息指示该第一资源为有效测量资源，终端设备确定该第一资源上的RLM测量结果是有效的。
在350中，终端设备根据该第一资源上的RLM测量结果，上报IS指示或OOS指示。
具体地，网络设备如果抢占到一个COT内的信道资源，则会判断用于终端设备进行无线链路监测的第一资源是否位于该COT内，若该第一资源位于该COT内，网络设备向终端设备发送指示信息，以指示该第一资源为有效测量资源，如果该第一资源没有位于该COT内，那么网络设备可以在之后的时间资源上来指示该第一资源是否为有效测量资源。终端设备接收到网络设备发送的指示信息后，如果发现该指示信息指示该第一资源为有效测量资源，那么终端设备可以认为该第一资源上的RLF测量结果是有效的。
应理解，如果终端设备在接收到该指示信息之前，已经在该第一资源上进行了无线链路监测并得到了RLM测量结果为IS或OOS，那么接收到该指示信息时，终端设备可以知道该RLM测量结果是有效还是无效的。例如， 如果该RLM测量结果是有效的，终端设备可以基于该RLM测量结果上报IS指示或OOS指示，如果该RLM测量结果不是有效的，那么终端设备可以不进行IS指示或OOS指示的上报。
如果终端设备在接收到该指示信息之前，还没有在该第一资源上进行无线链路监测，那么，该指示信息指示该第一资源为有效测量资源时，终端设备能够获知该第一资源上的RLM测量结果是有效的，于是可以在该第一资源上进行无线链路监测，并上报该第一资源上的RLM测量结果；如果该指示信息指示该第一资源并非是有效测量资源，那么终端设备可以不使用该第一资源进行无线链路监测。
因此，网络设备通过判断测量资源是否有效并指示给终端设备，使得终端设备能够在有效的测量资源上进行无线链路监测以及RLM测量结果的上报，从而提高了进行无线链路监测的准确性。
